About This Product
The JA Solar JAM54-D41 440W Bifacial Solar Panel is a high-efficiency solar module designed for residential and commercial grid-connected solar installations. Built with N-type TOPCon monocrystalline cell technology, this JA Solar panel combines bifacial energy generation with a durable black-frame construction.
The module uses 108 half-cut cells with a 16-busbar design to support efficient current collection and reliable electrical performance. Its bifacial construction allows the rear of the module to capture reflected sunlight where installation conditions permit, providing an opportunity for additional energy generation.
This Hawaii-specific variant, manufacturer part number JAM54D41-440MB-HI, features a glass-backsheet construction and factory-fitted genuine MC4-EVO2 connectors. It is designed for integration into properly engineered solar arrays using compatible mounting systems, inverters, and electrical protection equipment.
Who This Product Suits
The JA Solar JAM54-D41 440W Bifacial Solar Panel suits homeowners, solar contractors, and commercial installers looking for an N-type TOPCon module with bifacial capability and long-term manufacturer warranty coverage.
- Residential solar installations: Suitable for rooftop solar arrays where module efficiency, appearance, and reliable energy production are important.
- Commercial solar projects: Appropriate for grid-connected installations requiring consistent module specifications and compatibility with professionally designed solar systems.
- Bifacial installations: Well suited to elevated mounting arrangements and reflective surfaces where additional rear-side irradiance may improve energy yield.
- Hawaii installations: This specific HI variant is designated by the supplier for Hawaii customers and includes MC4-EVO2 connectors.
- Professional solar installers: Suitable for contractors designing systems in accordance with applicable NEC requirements, local electrical codes, and equipment compatibility specifications.
JA Solar’s bifacial technology is particularly useful where mounting geometry and surrounding surfaces allow meaningful reflected light to reach the rear of the module.
Specifications Explained
- 440W Rated Output: The module’s front-side nameplate power rating under standard test conditions, used for solar array sizing and electrical design.
- N-Type TOPCon Technology: Tunnel oxide passivated contact cell technology designed to improve carrier collection and reduce electrical losses.
- 108 Half-Cut Cells: Half-cell architecture helps manage internal resistive losses and supports efficient module operation.
- 16-Busbar Cell Design: Multiple current-collection pathways help reduce electrical resistance within the solar cells.
- Bifacial Monocrystalline Construction: Generates electricity from direct front-side sunlight and reflected light reaching the rear surface. Actual bifacial gain depends on site conditions.
- Black Frame: Provides a clean, consistent appearance for exposed rooftop installations.
- Glass-Backsheet Construction: Combines front glass protection with a rear backsheet as specified for this model.
- 1500V Maximum System Voltage: Supports appropriately designed DC solar arrays, subject to equipment ratings, temperature-corrected string voltage calculations, and applicable NEC requirements.
- MC4-EVO2 Connectors: Factory-fitted connectors for compatible DC wiring connections. Mating connector compatibility must be verified during installation.
- 25-Year Manufacturer Warranty: Manufacturer product warranty coverage subject to JA Solar’s applicable warranty terms.
- 30-Year Linear Performance Warranty: Long-term output warranty with a stated annual degradation rate of 0.40%, subject to the manufacturer’s warranty conditions.
- Hawaii-Specific Variant: Identified by manufacturer part number JAM54D41-440MB-HI and designated for Hawaii customers.
